They made a promise, and they don't plan on breaking that promise.
But Gabriel, Adrien's dad, hides Adrien from the world, after his mother dies.

(they don't know who each other's secret identities...yet.)
Its there final year, then high school is over for the two. Gabriel agrees that Adrien can go to school. But he has to listen to his dad and his rules.

But when he comes back, Marinette forgot the promise and there friendship.
But Adrien's not giving up yet, he'll do anything to get his lady's love.
